Problems solved by technology

[0004] In order to solve the problems existing in the prior art, the present invention specifically discloses a foundation treatment method based on the dynamic and precise control of uneven settlement. The method controls the vacuum degree of different areas in the foundation and then controls the settlement of the foundation, which can accurately treat The settlement process of the building body is caused by the uneven settlement of the foundation, and this method can be used to control the uneven settlement of the foundation when there are phenomena such as building tilting and foundation cracking caused by the uneven settlement of the foundation during the construction process and post-construction settlement , so that the project returns to normal state

example 1

[0038] The bearing layer (hard shell) of the natural foundation in a certain area is relatively thin, and the soil with a buried depth of about 4 m to 20 m is a muddy clayey soil with high compressibility, high sensitivity, low strength, and low permeability, with high water content. The porosity is large, the soil compression modulus is small, and the thickness is between 10 m and 25 m. It is the main weak underlying layer of the natural foundation. Now a residential building with a length of 38 m, a width of 21 m and a height of 32 m needs to be built on this foundation. Since the bearing layer is thin and the underlying soft soil layer is thick, in order to improve the bearing capacity of the foundation and accurately deal with the problems caused by the uneven settlement of the foundation, the foundation treatment method based on the dynamic and accurate control of uneven settlement can be used to treat this kind of Engineering needs to be processed.

[0042] A 5-story brick-and-concrete office building with a frame structure in a certain unit, with a plane size of about 76×18 m and a building area of ​​3 900 m 2. The geological conditions from top to bottom are miscellaneous fill, silty clay, silty silty clay, silty clay and silty clay. The maximum thickness of clay is 2.5m, and the thickness of silty clay is 3.5m~5.2m. In order to prevent and deal with the problems caused by uneven settlement of the foundation, the foundation treatment method based on the dynamic and precise control of uneven settlement can be used to treat the foundation.

[0043] The permeable piles are arranged with pipe piles, the pile caps are connected to the drainage pipes (branch pipes of the vacuum pipe network) and sealed with the prefabricated permeable piles, and the piles are driven below the groundwater level. The foundation is divided into unit areas, and each unit area is composed of 8 to 20 adjacent piles, and is equipped with a vacuum d...

Abstract

The invention discloses a foundation treatment method based on dynamic accurate control on nonuniform settlement. The method comprises the steps of (1) prefabricating a permeable pile, wherein a pile body is a hollow pipe pile; (2) connecting a pipe cap with a drain pipe, connecting the pipe cap with the prefabricated permeable pile hermetically, and driving the pile body to a position below the ground water level of a foundation; (3) dividing a treatment area of the foundation into unit areas, and configuring a vacuum draining pump for each unit area; (4) arranging a vacuum pipe network, ditching on the spot to bury all pipe sections into the foundation, and connecting an external interface with the vacuum draining pump; (5) arranging a mattress layer between a composite foundation and a base; (6) building the base, and then performing construction of an upper structure; (7) when nonuniform settlement of the foundation appears during building settlement, controlling the vacuum degree of different unit areas in the foundation by using the unit areas divided in the step (3) and the configured vacuum draining pump. By adopting the foundation treatment method disclosed by the invention, the settling amounts of different areas of the foundation are accurately controlled, and problems caused by nonuniform settlement are solved.

Description

[0001] technical field [0002] The invention provides a method for dynamically and accurately controlling the uneven settlement of the foundation, which belongs to the field of civil engineering. Background technique [0003] The foundation plays a decisive role in the building, and the quality of the foundation has a close relationship with the safety of the building. Due to the influence of various factors such as geological conditions, design and construction, the foundation is prone to uneven settlement, resulting in tilting and cracking of buildings, which are common accidents in engineering. Once a foundation accident occurs, it is difficult to remedy. For example, CFG pile composite foundation engineering, uneven settlement during construction cannot be controlled. How to accurately control the uneven settlement of the foundation during the settlement of the building body and ensure the architectural form and safety of the building has become a difficult problem. ...
